This thread is interesting. I used to have a huge fucking WoW addiction, but I dated a guy who played with me, so it was OK for a time. He wanted to quit playing, I still played and it put a strain on our relationship.
Forums, working on the Internet and all that jazz has put a strain on my last relationship. It sucks. I was accused of being cold and never wanting to be intimate. There were reasons why I was like that, but for the most part, I preferred Internet company to listening to his pothead rants.
The WoW addiction was the worst though. It wasn't until he left that I finally woke up and quit playing.
